Answer :
1/5 full =250g
4/5 full =550g
550g-250g=300g=3/5 without jug
1/5 without jug=300g/3=100g
250g-100g=150g
The jug weighs 150g empty
4/5 full =550g
550g-250g=300g=3/5 without jug
1/5 without jug=300g/3=100g
250g-100g=150g
The jug weighs 150g empty
The weight of the jug when empty will be 150 grams.
The relationship between the weight of the jug and volume of water can be expressed as :
1/5 full = 250 grams
4/5 full = 550 grams
Change in weight of jug :
4/5 - 1/5 = (550 - 250) grams
3/5 = 300 grams
This means that 1/5 grams of fluid in the jug is :
300 grams ÷ 3 = 100 grams
The weight of the jug when empty would be ::
Weight when 1/5 full - Weight of 1/5 or fluid in the jug
250 g - 100 g = 150 grams
Therefore, the weight of the empty Jug is 150 grams.
